b8ddc16027 refactor: return QueryPath from resolve_query, add mock upstream to tests
resolve_query now returns (BytePacketBuffer, QueryPath) so callers
and tests can inspect the resolution path without reading the query
log. Production call sites (UDP, DoT, DoH) destructure and ignore it.

The forwarding test now uses a mock UDP upstream that replies with a
canned response, asserting QueryPath::Forwarded instead of != Local.

115a55b199 fix: bracketed IPv6, localhost SAN, split host-check helpers
- is_doh_host split into strip_port + is_loopback_host + is_tld_match
- strip_port handles bracketed IPv6 ([::1]:443) and rejects bare IPv6
- Add [::1] to accepted loopback hosts, add localhost DNS SAN to cert
- Remove dead sans.is_empty() guard (loopback IPs always present)

3665deb56b fix: accept loopback addresses for DoH and add IP SANs to TLS cert
The DoH endpoint rejected requests with Host: 127.0.0.1/::1/localhost,
and the generated TLS cert had no IP SANs — so browsers couldn't use
https://127.0.0.1/dns-query even with the CA trusted.

- is_doh_host now accepts 127.0.0.1, ::1, localhost (with optional port)
- TLS cert includes 127.0.0.1 and ::1 IP SANs, plus bare TLD DNS SAN

Closes #87

2101dfcf17 feat: transport protocol tracking (UDP/TCP/DoT/DoH) with dashboard visualization
Thread Transport enum through resolve pipeline, record per-query
transport in stats and query log. Dashboard gets bar chart panel
with encryption %, transport column in query log, and filter dropdown.

571ce2f013 feat: background refresh on stale cache hit (RFC 8767 revalidation)
When a cached entry is expired but within the 1-hour stale window,
serve it immediately with TTL=1 AND spawn a background re-resolve.
The next query gets a fresh entry instead of another stale serve.

Without this, stale entries were served repeatedly for up to an hour
with no refresh — effectively ignoring TTL.

7efac85836 feat: wire-level forwarding, cache, request hedging, and DoH keepalive
Wire-level forwarding path skips DnsPacket parse/serialize on the hot
path. Cache stores raw wire bytes with pre-scanned TTL offsets — patches
ID + TTLs in-place on lookup instead of cloning parsed packets.

Request hedging (Dean & Barroso "Tail at Scale") fires a second
parallel request after a configurable delay (default 10ms) when
the primary upstream stalls. DoH keepalive loop prevents idle
HTTP/2 + TLS connection teardown.

Recursive resolver now hedges across multiple NS addresses and
caches NS delegation records to skip TLD re-queries.

Integration test harness polls /blocking/stats instead of fixed
sleep, eliminating the blocklist-download race condition.

7d6b0ed568 feat: DoH server endpoint + DoT enabled by default (#79)
* chore: document multi-forwarder and cache warming in config and README

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: DNS-over-HTTPS server endpoint (RFC 8484)

Serve DoH at POST /dns-query on the existing HTTPS proxy (port 443).
Automatically enabled when proxy TLS is active — no config needed.
Also fix zone map priority so local zones override RFC 6762 .local
special-use handling.

* style: cargo fmt

* chore: remove GoatCounter analytics from site

GoatCounter domains (goatcounter.com, gc.zgo.at) are blocked by
Hagezi Pro, which is Numa's default blocklist. A DNS privacy tool
should not embed analytics that its own resolver blocks.

* feat: enable DoT listener by default

DoT now starts automatically with `sudo numa`, matching the proxy and
DoH which are already on by default. The self-signed CA infrastructure
is shared with the proxy, so there is no additional setup. This makes
`numa setup-phone` work out of the box.
